Description
Idrettsbane-overflatemateriale.Sports field surface material.
Foreliggende oppfinnelse vedrører syntetiske idrettsbane-overflatematerialer og spesielt angår oppfinnelsen slike materialer egnet for innendørs såvel som utendørs bruk for sportsaktiviteter slik som fotball, friidrett, golf, osv. The present invention relates to synthetic sports field surface materials and in particular the invention relates to such materials suitable for indoor as well as outdoor use for sports activities such as football, athletics, golf, etc.
Tidligere forsøk på å fremstille slike overflatematerialer har benyttet seg av termoplastiske materialer av lav-denier-garn, f.eks. 60-70 denier, laget i teppeform ved tufting eller lignende metoder. Slike lav-denier-materialer var ikke vellykkede siden de bibeholdt vann i luven. En annen kjent overflate anvender høy-denier (f.eks. over 500)-rektangulære flate strimler som luv og dette kan tuftes gjennom teppe-fremstillingsprosesser og festes i et underlagsmateriale med et klebemiddel. Previous attempts to produce such surface materials have used thermoplastic materials of low denier yarn, e.g. 60-70 denier, made in carpet form by tufting or similar methods. Such low-denier materials were not successful as they retained water in the pile. Another known surface uses high-denier (eg above 500) rectangular flat strips as pile and this can be tufted through carpet manufacturing processes and attached to a backing material with an adhesive.
Disse kjente materialer opptar belastning ved hjelp av tettpakkede lav-denier-filamenter i det første tilfelle, og i det andre tilfelle ved hjelp av strimler som hver har en forutbestemt bestandighet overfor bøying. These known materials absorb load by means of tightly packed low-denier filaments in the first case, and in the second case by means of strips each having a predetermined resistance to bending.
Naturlig gress omfatter imidlertid et forsterket filamentmateriale fylt med cellulose, luft og vann og har en bestemt motstandsevne overfor bøying og ved overskridelse av denne bestandighet bøyes gresset, og gjeninntar sin form ved fjerning av belastning. Man antar at denne bøying eller plutselige sammenbrudd gir naturlig forekommende gressmatter deres "fjærende" og "spenstige" karakter. Natural grass, however, comprises a reinforced filament material filled with cellulose, air and water and has a certain resistance to bending and when this resistance is exceeded, the grass bends and regains its shape when the load is removed. It is thought that this bending or sudden collapse gives naturally occurring grass mats their "springy" and "resilient" character.
Et formål med foreliggende oppfinnelse er å tilveie-bringe et kunstig gresslignende materiale som kan simulere bøyeeffekten og derved gi egenskaper av naturlig forekommende gressmatte-materiale. One purpose of the present invention is to provide an artificial grass-like material which can simulate the bending effect and thereby provide properties of naturally occurring grass mat material.
Ifølge foreliggende oppfinnelse er det således tilveiebragt et syntetisk gresslignende idrettsbane-overflate-' materiale som omfatter blader av termoplastisk materiale anordnet i det vesentlige opprettstående i et underlag, hvor hvert blad har en tverrsnittsform som bevirker at bladet krummes eller bøyer seg ved en bestemt bøyebelastning, slik at bladets motstandsevne overfor bøying plutselig minsker over nevnte bøye-belastning . According to the present invention, there is thus provided a synthetic grass-like sports field surface material comprising sheets of thermoplastic material arranged substantially upright in a substrate, each sheet having a cross-sectional shape which causes the sheet to curve or bend under a certain bending load, so that the blade's resistance to bending suddenly decreases above said bending load.
Det termoplastiske materiale er fortrinnsvis nylon, skjønt andre materialer som gir gjenvinning av bladet når belastningen fjernes, også er egnede. Krummeegenskapen kan oppnås ved hjelp av forskjellige tverrsnitt, slik som f.eks. et hult sirkulært rør, men fortrinnsvis har bladene i tillegg en selektiv bøyeretning. For særlig å hjelpe tilveiebringelsen av en selektiv bøyeretning, kan hvert blad ha en ikke-ensartet tykkelse betraktet i tverrsnitt. Egnede former for tilveiebrin-gelse av denne ytterligere egenskap omfatter hule, rektangulære boksformede snitt. Ikke-hule tverrsnittsformer slik som I-snitt, L-snitt, Z-snitt kan også anvendes. L-snitt kan ha vinkler på mellom 60 og 120°. The thermoplastic material is preferably nylon, although other materials which provide recovery of the blade when the load is removed are also suitable. The crumb property can be achieved by means of different cross-sections, such as e.g. a hollow circular tube, but preferably the blades also have a selective bending direction. To particularly assist in providing a selective bending direction, each blade may have a non-uniform thickness when viewed in cross-section. Suitable forms for providing this additional property include hollow, rectangular box-shaped sections. Non-hollow cross-sectional shapes such as I-section, L-section, Z-section can also be used. L-sections can have angles of between 60 and 120°.
Foretrukne bredder, d.v.s. maksimale tverrsnitts-dimensjoner på bladene, er i området 100-5000 mikron og foretrukken veggtykkelse er i området 10-100 mikron. Veggtykkelsen og/eller den maksimale tverrsnittsdimensjon kan variere langs bladets lengde. Preferred widths, i.e. maximum cross-sectional dimensions of the blades are in the range of 100-5000 microns and preferred wall thickness is in the range of 10-100 microns. The wall thickness and/or the maximum cross-sectional dimension may vary along the length of the blade.
Egnede bladlengder er i området 6,4-12,5 mm, idet en lengde på 9,5 mm foretrekkes for mange anvendelser. Bladene kan dannes av filamenter med en denier i området 200-700, idet omkring 300 er spesielt egnet for mange anvendelser. Suitable blade lengths are in the range 6.4-12.5 mm, with a length of 9.5 mm being preferred for many applications. The blades can be formed from filaments with a denier in the range 200-700, with around 300 being particularly suitable for many applications.
Bladene kan være krympet etter dannelse av dets tverrsnitt, og dette gjør at den belastning hvorved krumming finner sted kan minskes avhengig av den ønskede elastisitet eller spenstighet. The leaves can be shrunk after forming its cross-section, and this means that the load at which curvature takes place can be reduced depending on the desired elasticity or resilience.
Bladene er fortrinnsvis anbragt tett sammen i et underlag og er festet til dette ved hjelp av et klebende belegg. The leaves are preferably placed close together in a substrate and are attached to this by means of an adhesive coating.
Strukturen kan fremstilles ved anvendelse av en normal teppefremstillingsprosess inkludert tufting, og legges fortrinnsvis for bruk på et elastisk eller fjærende underlag, f.eks. et polymerskum. Typisk vil bladtettheten være i området 186-372 blader pr. cm 2. Materialet som utgjør bladene er vanligvis pigmentert grønt slik at det skal se ut som gress. The structure can be produced using a normal carpet manufacturing process including tufting, and is preferably laid for use on an elastic or resilient base, e.g. a polymer foam. Typically, the leaf density will be in the range of 186-372 leaves per cm 2. The material that makes up the leaves is usually pigmented green so that it looks like grass.
Videre kan pollengden og antallet av blader pr. enhetsareal varieres avhengig av den aktivitet for hvilken overflaten skal anvendes. Furthermore, the amount of pollen and the number of leaves per unit area is varied depending on the activity for which the surface is to be used.
I en foretrukken utførelse av oppfinnelsen omfatter en idrettsbane-overflate nylonfilamenter av L-form i tverrsnitt og dannet av et 300 denier-materiale. In a preferred embodiment of the invention, a sports court surface comprises nylon filaments of L shape in cross section and formed from a 300 denier material.
Grupper av 18 filamenter hver med en lengde på 19 mm er tuftet inn i et polypropylen-skrim-stoff ved en tetthet på 2,1 tufter pr. cm bredde og 4 tufter pr. cm lengde av stoffet. Den resulterende overflate har således omkring 295 blader pr. cm 2, med filamentendene beliggende omkring 9,5 mm fra skrimmaterialet. Groups of 18 filaments each with a length of 19 mm are tufted into a polypropylene scrim fabric at a density of 2.1 tufts per cm width and 4 tufts per cm length of fabric. The resulting surface thus has about 295 leaves per cm 2, with the filament ends located about 9.5 mm from the screen material.
Et lag av låsemateriale er anbragt på den side av skrimmaterialet som er motsatt liggende den side fra hvilken filamentene utrager, for å holde filamentene i stilling, og et lag av fjærende eller elastisk underlagsmateriale er festet til laget av låsemateriale. A layer of locking material is placed on the side of the screen material which is opposite to the side from which the filaments protrude, to hold the filaments in position, and a layer of springy or elastic base material is attached to the layer of locking material.
